Abstract

En 中文
Wild animals sold as pets are at a higher risk of extinction than animals that are not traded. Invertebrates are often overlooked in national and international laws designed to control the global pet trade. Among these invertebrates, terrestrial isopods—which function as detritivores—have traditionally been kept to clean terraria housing vertebrates and other arthropods. Over the past 2 decades, they have gained popularity among hobbyists due to their ease of care, vibrant colors, minimal space requirements, and harmlessness to humans. Many traded species have limited distribution areas, sometimes only a single locality. Collecting these species in the wild poses a threat to local populations. Species are continuously being added to the online market. Many of these species, especially from tropical regions in Southeast Asia, Central America, and South America, have not been described scientifically. In addition to threatening native populations, this trade in live specimens increases the probability of non-native species introductions and invasions to new regions. Given this growing interest, we advocate for including terrestrial isopods in national and international regulations. We encourage scientists to assess the scale of the terrestrial isopod pet trade, scientifically describe traded species, and collect distribution and ecological data. We ask the International Union for Conservation of Nature to establish a terrestrial isopod specialist group to assess the status of traded species, which would facilitate their inclusion in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. We urge policy makers to make conservative lists of species that can be traded applying the precautionary principle in regulating the trade in species with an unknown conservation status and invasion risk.
